Elastomer Rod End

What do think about this? Anybody used it yet?

They simply call it "elastomer", no specs on the material used. Kinda expensive though.

They even have an elastomer trailing arm bushing but it's for the GM "G Body"

Yes, they work well. Sure improve lifespan of the rod end and keep dirt out. Easy to lube behind them w/ a needle too.

The elastomer rod end look nice, a rod end is a rod end, 5/8 will fit, 3/4 is kinda large (nowhere used in our cars, the sleeves are all 5/8 threaded)
As for the trailing arm bushing, similar to a johnny joint. If the hole for the bolt is 1/2" you can use it, the trailing arm can simply be cut and have a proper ID sleeve welded in (or on) so this bushing can be pressed in. The johnny joint comes with a weld in sleeve already.
